Application filed January 9, 1907. Serial No. 351,538,

T 0 all whom 'it may concern:

Be it known that l, HARRY LAWRENCE WILLIAMS, a' citizen of the United States, resi v at; Denver, in the county of Denver and State of Colorado, have invented neu and useful Improvements in Railway-Ties, of which the following is a specilication.

This invention relates'to railway ties of the type embodying a metal shell or casing containing aiilling of cement or other nioldable material, and has for its objects to provide a comparatively simple, inexpensive device of this character 'which Will be exceedingly 'strong and durable, one wherein the filling will be retained firmly and securely in place Within the casing, and one Awherein the casing.

is a side elevation of a tie embodying the inn vention and showing a pair of rails in position thereon. Fig. 2 is a vertical section taken centrally and longitudinally through the tir Fig. 3 is a view of the blank from which casing is formed and showing the same prior to bending into shape. l Fig. 4 is a detail cross section vtaken on the line ee-4 of Fig-1. Y

Referring to the drawings, it will he seen. that the tie as a y.Whole comprises an outer casing 1 composed of sheet metal or other suitable material and a bodyportion or filling 2 made from cement or other suitable moldable material and constituting the tie proper,l which in practice is extended transversely between and for supportingthe overlying rails 3, as Yusual indevices cfzthis character.

The casing l, which comprises a top portion or Wall 4, side portions Vor Walls 5 and end portions or Walls 6, is composed ol a single piece or blank ol" sheet metal of the form shown in Fig. 3 and produced by stamping or otherwise, the blank being finally bent into shape to produce the completed easing which is of substantially hexagonal form in cross section, as seen in Fig. e. The end portions 6 of the blank are of a Width somewhat greater than that of the completed casing, thus providing engaging portions or flanges T which in the completed casing are folded inwardly into engagement With the side walls 5 for preventing relative spreading of the latter, While struck from the portion 4 of' the blank, which is provided at points suitably remotefrom its ends with openings 8, is a pair of rail engaging members or tongues 9 spaced relative to` the respective openings 8 and bent -as shown in Fig. 2 for engagement with' the outer edges of the rails, there heingformed 'in the end Walls 6 o enings or periorations 10, for a. purpose which will presently appear.

The side portions 5 of the casing are bent transversely along the dotted lines 11 Whereby the inner faces -of said Walls Will, in the completed casing, be of concaved form, thus reducing the Width of the casing at its to and bottom, which latter is open to permit introduction or' the cement lling 2, or that is, to render the open bottom of lesser diameter than that ofthe casing at a point above the bottom thus to retain the ilhng in place Within the casing.

Entered longitudinally into the casing through the perforations 10 are tie rods or members 12, the inner ends of which are eX- tended upward through the openings 8 and terminally bent into the form of rail engaging portions or hooks 13, which engage the bases of the rails 3, there being threaded onto the outer ends of the rod tensioning members or nuts 14 through the medium ofWhich the rods may be drawn into secure clamping engagement with the rails. It will be observed in this connection that the rods 12, which are inserted through the cement filling 2 While in a plastic state, serve not only as clamps for' the rails but also to brace the tie at points beneath the latter and as auxiliary means for retaining the cement illing in place Within the casing 1.

In practice, after the ties have been completed and in assembling the rails in position thereon, the outer edges of the base portion of the rails are seated beneath the engaging lugs 9 and the inner ends of the rods 12 folded down upon the inner edges of the rail bases in the form of the hooks 13, after which the ends le are manipulated for tensioning the rods 12 to securely clamp the rails in place, it being observed that owing to the side walls 5 of the casing being of internally concaved form, the cement filling after hardening will beretained-seourely in place Within the casing, the filling being lrther se-r 1'. A rail tie comprising a shell of sheetI metal, side extensions bent downwardly, end

extensions bentdownwardly and having their side edges bent laterally over the side extensions to' prevent spreading of the latter, means for securing rails to the tie, and s. i'illing of plastic material in the shell.

2. A rail tie comprising 'a shell of sheet metal, side extensions bent downwardly, end extensions bent downwardly and having their'iside edges bent laterally over the side extensions to prevent spreading of the latter, rail fastening means serving to prevent the end extensions from spreading and moving out of engagement with the side extensions, and a body of concrete contained in the shell.-

- 3. A rail tie comprising a sheet metal body l having end and side extensions bent downwardly to forni a easing open at its bottom, there being provided apertures in the top and verticalwalls of the casing, vlugs stamped upwardly from the top of the Casin for engaging the rail bases, a illing of mol able material in the casing, bars extending through the material and through the apertures of the easing, a hook on one end of each bar for engaging the base of arail, a thread on theopposite vend, and a nut on the threaded end earing against the outside ofthe cas' the edges of the end extensions being boliialiterv ally to overlap the side extensions and prevent spreading-of the latter.

.In testimonywhereof, I aiix my signature in presence of two"wi`tnesses a HARRY LAWRENCE WILLIAMS.
